Abstract (en)

[origin: WO2014013450A1] A method for manufacturing tubular supports (4) designed to support respective diamond cutting members (3) to obtain diamond beads (5) coupled to a flexible support structure (2) for manufacturing a wire (1) for cutting slabs from blocks of stone material. The method comprises the following steps: providing at least one metallic laminar element (6) defining a longitudinal axis (R) that includes a pair of edges (7) at opposite sides with respect to the axis (R); bending the at least one metallic laminar element (6) around the axis (R) up to the reciprocal matching of said edges (7); permanently joining the edges (7); obtaining the tubular support (4). Upon the bending step the at least one laminar metallic element (6) includes at least one operative face (10) having a plurality of grooves and/or recesses (11) spaced apart each other susceptible to define the inner wall (12) of the tubular support (4). The grooves and/or recesses (11) are made so as to define a plurality of receptacles (11') susceptible to house the polymeric material of the spacer elements (9) upon manufacturing the cutting wire (1).
